Cursive Macroexpander

gistfile1.txt

The other new feature is an interactive macroexpander. It requires a REPL to perform 
the actual expansion, with the current namespace loaded into it. Start by executing 
Tools->REPL->View Macro Expansion. This will select the nearest surrounding macro 
form and display it in a popup window. You can move the cursor anywhere within the 
form and either click the right arrow in the toolbar or use Ctrl/Cmd-right - this 
will expand the nearest surrounding macro form and all forms above it up to the 
top displayed form - the cursor will be left at the start of the innermost form 
that was actually expanded. Give it a try, it’s less confusing than it sounds! 
There are also various controls in the toolbar for various sorts of prettification - 
you can show and hide metadata, tidy up referred vars and imported classes etc. This 
expander should be much more accurate than most, it correctly maintains &env when 
expanding and does its best with metadata. Currently this only works for Clojure 
macros, but I’ll add support for expanding ClojureScript macros soon.
